Finally, Nests!

The two boxes that have had no sign of bluebirds have nests! Finally. Maybe it's the steady warm weather.

Box 1: 4 eggs (I removed one egg that had a cracked shell. It felt lighter than the other 4 eggs, and when I broke it open, it was definitely a goner.)
Box 2: 4 eggs
Box 3: down for cleaning
Box 4: down for cleaning
Box 5: nest (first nest in three years)
Box 6: nest (first nest this year)
